| 摘 要： | 测定了VOSO4与天冬氨酸(asp)和邻菲罗啉(phen)及联吡啶(bipy)三元体系在不同酸度(pH=1-14)的乙二醇-水(1:1)溶液中低温ESR波谱,发现不同pH下生成不同组成和结构的络合物,利用Johnson加合规则并配合IR推测了它们的可能结构,利用电子光谱数据,计算了络合物晶体场参数。

| Abstract: | ESR spectra of VO-asp-phen and VO-asp-bipy ternary systems in glycol and water (1:1) solution at various acidity have been observed at low temperature. It has been found that in different pH range the different structural complexes have formed. According to Johnson's rule and IR their possible structures were suggested. Using electronic spectral data, the crystal field parameters were calculated. |
